Is the Acura RDX bigger than the RAV4?

Yes—the Acura RDX is larger in exterior size than the Toyota RAV4, typically being longer and wider. However, the RAV4 often offers more cargo space with the rear seats up, so “bigger” can depend on what you value most. This article breaks down the key differences in size, space, and practicality.

To understand how the two models compare, it helps to look at exterior dimensions, interior space, and cargo capacity. The numbers can vary slightly by model year and trim, but the overall trends remain consistent across recent generations.

Exterior footprint: how the two compare

What to measure and why

Before listing the main exterior metrics, note that these measurements reflect current-generation models (roughly 2020–2025) and may vary by trim and year.

• Exterior length: RDX is generally longer than the RAV4—roughly 186–190 inches for the RDX versus about 180–184 inches for the RAV4.


• Exterior width: The RDX tends to be wider, around 74–76 inches, while the RAV4 sits in the low 73–74 inches range.


• Wheelbase: The RDX typically has a longer wheelbase, roughly 108–110 inches, compared with the RAV4’s approximate 105–106 inches.


• Height: The RDX generally stands around 63–66 inches tall, while the RAV4 sits a bit taller at roughly 66–67 inches depending on trim.

In short, the RDX occupies more length and width on the road, giving it a larger exterior footprint overall. The RAV4 remains a compact SUV, and its styling can feel more nimble in urban environments despite offering competitive interior space.

Interior space and practicality

Cargo and passenger space

Before listing the numbers, here’s a quick look at how cabin space compares when you’re inside the vehicle and loading gear.

• Passenger volume: The RDX generally provides slightly more passenger space, with total cabin volume around the low 100s of cubic feet, versus the RAV4 which sits a bit under that mark.


• Cargo behind the second row: The RAV4 typically offers more cargo capacity with the rear seats up—roughly 37–38 cubic feet—compared with the RDX’s roughly 29–30 cubic feet.


• Maximum cargo space (seats folded): The RAV4 again tends to edge out the RDX, with around 68–70 cubic feet versus the RDX’s roughly 58–60 cubic feet.

Overall, the RDX emphasizes a roomier and more upscale passenger cabin, while the RAV4 prioritizes greater cargo versatility and utility when the rear seats are folded.

Summary

For buyers focused on exterior size, the Acura RDX is bigger than the Toyota RAV4, especially in length and width. If cargo flexibility with the rear seats folded is your priority, the RAV4 commonly offers more total cargo room. Ultimately, the choice depends on whether you value a larger physical footprint and premium interior (RDX) or greater cargo capacity and SUV practicality (RAV4).
